The volume of a sphere is `.176 m^3` What will be the volume of 25 such spheres taking into account the significant figures.

Options

A. `44.0m^3`
B. `44 m^3`
C. `404.0m^3`
D. `0.404 m^3`

Answer

(a)

Explanation

Here, volume of sphere `= 1.76 m^3`
(three signigicant figures).
Volume of 25 spheres `= 25 xx1.76m^3 = 44.00 m^3`
As number of significant figures in volume of spheres in 3 and it must remain same in the final result as well.
`:. Volume of 25 spheres = 44.0 m^3`
